We propose the implementation of a quantum heat pump with ultracold atoms. Itis based on two periodically driven coherently coupled quantum dots usingultracold atoms. Each dot possesses two relevant quantum states and is coupledto a fermionic reservoir. The working principle is based on energy-selectivedriving-induced resonant tunneling processes, where a particle that tunnelsfrom one dot to the other either absorbs or emits the energy quantum$\hbar\omega$ associated with the driving frequency, depending on its energy.We characterize the device using Floquet theory and compare simple analyticalestimates to numerical simulations based on the Floquet-Born-Markov formalism.In particular, we show that driving-induced heating is directly linked to themicromotion of the Floquet states of the system.
